I seek it, but don't force it. Though less frequently than x /RDLH. But that is because I face more people who try standing passes than kneeling passes. I believe it is valuable. It doesnt have to be your go-to guard, just fill a few holes.

It gives you a good compliment to a arm drag/butterfly sweep game against kneeling/combat base opponents.

There are good mount and back mount escapes that involve going to DHG as well

I onlywoken the basics. I usually end up inserting my far hand so I have both arms inbetween their legs and bump up into my opponent, landing in their guard. This movement is facilitated by my opponent shifting their weight backwards to avoid me coming out the back door.

I would recommend practicing new grappling movements without strikes until you feel at least a little confident with them. Then progressively add pressure.

For further information both Ryan hall and Jeff glover have excellent instructionals out that make for great resources as well.

Sounds good. You just have to take it Incrimentally. I started with just entries, and didn't care if I would sweep. I just found it hard as hell to get under people.

And it doesnt have to be the number one on your priority list. I never Played deep half untill I got my brown belt. And it wasn't out of need... It was out of desire. I simply wanted to know for the sake of knowing it.

I'm a DHG man but if you want to play it with strikes you'd better be hella active so you always keep the top guy unbalanced or really good at reclaiming full guard if you fail at sweeping. Preferably both.

Without strikes one can usually unnerve the top guy by playing with his balance making him over-commit to one side and then boom you go the other way. That's a much more patient way of playing which does not translate well to MMA at all.

Like turtle, it is more of a transitional position than anything else. I play a heavy butterfly/X-guard game, so it is a natural progression for me... And although I have a LOT of luck with DHG, it doesn't seem to lend itself to anything spectacular, in my experience. I usually end up in half guard with my opponent's leg over my shoulder, blocking my full pass, or in a potential back-take opportunity where they usually roll back into open guard. I would rather look for X variations that leave me in a better finishing position.
